Title: Method of and apparatus for producing plied spun staple yarn
IPC: D02G3/28
Filed: 1975-06-09
Abstract: 1507535 Making yarns UNIROYAL Inc 9 June 1975 [11 June 1974] 24646/75 Heading D1F In order to produce plied spun staple yarn 41 one spun staple yarn 11 is ballooned around a second spun staple yarn 31 at a ballooning station 6. Each yarn 11. 31 is withdrawn from the respective supplies 4, 30 by respective pairs of nip-forming rolls 13, 14 and 26, 27 at equal linear speeds. The roll pairs isolate the tensions on the yarns such that the tension on each yarn before it reaches the respective roll pair is different from the tension after it has passed the roll pair. A roll 28 draws the plied yarn 41 and the respective yarns 11, 31 at a speed greater than and, as a result, at a tension greater than that imparted to each yarn by the roll pairs 13, 14 and 26, 27 to maintain the stability of the balloon. The ballooning operation imparts a false twist on the yarns 11, 31 and the plied yarn 41. The plied yarn is then guided via a roll 34' to a heat-treatment zone 7 where it enters a steam-heated tube 62 and exits from another heated tube 63 so that the already twisted yarn 41 is heat-set to retain the twist. The twist-set yarn is guided around rolls 36, 37, pigtails 38, 39, rolls 42 and 34" so that it dries and cools before being passed under increased tension to a yarn take-up means 8. The roll 34" is smaller in diameter than its original roll 34' whereby the yarn travelling speed around the roller 34" is decreased. Therefore the tension imparted to the yarn 41 inside the tubes 62, 63 is small compared to the tension on the yarn 41 as it leaves the roll 28. The tension subjected to yarn 51 after it has left the drying and cooling zones is increased. The heating in the zone 7 may be in the form of moist heat or dry heat. The rolls 13, 26 and 18 are driven at equal rotational speeds and the rolls 13 and 26 have a high friction slippage-preventing surface which in the case of the roll 26 is made of aluminium oxide. The rolls 34' and 34" have also a high friction surface similar to the rolls 13, 26 and 18. The plying and ballooning of the yarn 11 around yarn 31 is promoted by a disc 24 rotating about a housing 74 at the plying station 6.

Abstract: 1,124,963. Renewable strip filters for liquids. M. E. L. EQUIPMENT CO., Ltd. 6 May, 1966 [11 June, 1965], No. 24759/65. Heading B1D. The apparatus comprises liquid-pervious means for supporting a portion of a strip of filter medium, the portion forming at least part of a means for receiving a flow of unfiltered liquid, normally-stationary means which are operable to move the strip of filter medium to replace that portion of the strip with a fresh portion, and means responsive to variations in the weight of liquid in the receiving means which bring the movable means into operation automatically when the weight exceeds a predetermined value. As shown, a liquid-pervious endless belt 9, 11 is formed into a trough at its upper run by two pairs of longitudinally-spaced sprockets 12, 13, between which the upper run sags, and by two transversely-spaced bars 36 arranged in the region between the sprockets. The trough supports a portion of a strip of filter medium 6 of paper, cloth or the like, drawn from a roll 7 and eventually disposed of in a bin 22. During filtration, the endless belt is stationary, but when, owing to clogging of the filter medium, the weight of liquid in the trough exceeds a predetermined value, a transverse lever 23, pivoted to the far side of casing 1 at 24, spring-supported (29) at its nearer end, and supporting the trough at spaced points along it, tilts to close a micro-switch 28. The switch controls a motor 18 which drives the belt by a further sprocket 17, and opens when the clogged portion has been moved on. In another embodiment, not described in detail, the filter medium is associated with a perforate plate at the bottom of a tank, and the tank is pivotally supported so that it moves about the support point to actuate the switch when appropriate.

Title: Improvements in load compensating fluid pressure brake equipment for railway vehicles
IPC: B60T8/18
Filed: 1955-08-30
Abstract: 771,988. Fluid-pressure railway brakes. WESTINGHOUSE AIR BRAKE CO. Aug. 30, 1955 [Aug. 30, 1954], No. 24829/55. Class 103 (1). Load compensating fluidpressure brake equipment for railway vehicles comprises a mounting bracket 1, which may be suitably mounted on a spring-supported portion of a vehicle, by means not shown, and a strut cylinder device 2 consisting of a vertically disposed cylinder casing in which is slidably mounted a control piston 6 having a piston stem 7 which extends through and is slidably guided in a head 8 pressed into the upper end of the cylinder casing, the stem 7 having at its upper end an adjustable screwed contact member 54 adapted to engage an unsprung portion of the vehicle to thereby gauge the weight of the load on the vehicle. In operation fluid under pressure supplied to strut cylinder device 2 flows through a hose nipple and by passages in the bracket 1 and a gasket 4 between the bracket and cylinder device 2 to supply passage 16 and to pressure chamber 15 below the piston 6. When the fluid pressure in chamber 15 becomes sufficient to overcome the opposing force of spring 20, piston 6 is moved upwardly until a contact member 54 engages a stop-member on an unsprung part of the vehicle to gauge the weight of the load. When piston 6 passes the pair of ports 31, Fig. 13, in its upward movement, fluid-pressure supplied to chamber 15 will flow through these ports, passage 28, opening 55 in gasket 50, other passages in bracket 1 and a further hose nipple whence it will flow to the selector valve device to condition the associated brake equipment for braking a partially loaded vehicle. Similarly, with other degrees of loading, the piston may pass the pairs of ports 25, 26 or 27 to connect them to the pressure chamber 15. Thus gaskets 50, 57, or 60, as shown in Figs. 9-11, may be fitted between the bracket 1 and cylinder 2 so as to provide communication through, or blank off the appropriate ports according to the downward displacement of the spring vehicle structure under its load.

Title: Improvements relating to weighing scales
IPC: G01G1/26
Filed: 1928-08-31
Abstract: 321,489. Marks, Sir G. C., (Toledo Scale Co.). Aug. 31, 1928. Computing-apparatus; loose-weight apparatus. -Relates to weighing-scales of the kind in which means are provided for increasing the normal weighing capacity of the scale and for indicating the weight and monetary value of the commodity, the indicating means being such that they will automatically accommodate themselves to changes in the weighing capacity of the scale. According to the invention the weighing scale comprises an automatic weighing mechanism operatively connected with one of two co-operative indicator elements in the form of a rotatable chart having a number of sets of value-indicating scales, and an indicator arm movable about the axis of the rotatable chart and positioned for direct cooperation with the chart, a capacity-increasing mechanism adapted for supplementing the automatic weighing mechanism and provided with a device for rotating the chart to bring a different set of value-indicating scales into co-operative relation with the indicator arm and an indicator aperture or window which exposes, throughout their entire length, the value-indicating scales of the set which is moved into co-operative relation with the indicator arm. A yoke 27 for receiving the capacity-increasing weights 30 is suspended from a weighbeam 3 coupled by a flexible band to a pendulum lever 20 carrying an inclined indicating hand 23 co-operating with a cone-shaped weight and value chart 19. The weighing capacitv of the scale is increased by turning an external knob on a cam shaft 44 thereby causing cams 47 successively to lower weight-carrying levers 35 and deposit the weights' 30 upon the yoke 27. At the same time a chain connection 50 rotates the cone-shaped chart 19 through a corresponding angle so as to bring into view a new range of weight and value figures appropriate to the altered weighing capacity. When the carrying-levers 35 are raised to remove the weights from the yoke, pins 41 on the levers rock clamping fingers 39 so as to engage the weights and prevent accidental derangement of the parts.
